A lovely photo, well done.
My only constructive comment is that the 'lead line' (the river) leads the eye out of the left side of the photo.
Maybe shifting your shooting position to place the river further right might have improved the composition - but I guess the sun might be in the wrong place then - ah well!

This is a great image to start on TE with, welcome! we are lucky that you had the time to take the picture before leaving it's very nice, I especially like the the left side of the image with the bridges and the boat (gondola?) so I made a WS to put the focus on it. but I can't post it as you didn't check the box to allow work sho please do and you'll get very good ideas of different ways of post processing
